            The process of getting an email from one person to another over a network or
			the Internet involves many systems working together.  Each of these systems
			must be correctly configured for the process to work.  The sender uses a <span class="em emphasis">Mail
			User Agent</span> (MUA), or email client, to send the message through one or more
			<span class="em emphasis">Mail Transfer Agents</span> (MTA), the last of which will hand it off to a 				<span class="em emphasis">Mail Delivery Agent</span> (MDA) for delivery to the 
			recipient's mailbox, from which it
			will be retrieved by the recipient's email client, usually via a POP3 or IMAP server.
